Filed: 1979-06-05
Abstract: PURPOSE: To realize the high-accuracy automatic measurement with no effect of noise received, by carrying out the measurement of the weight based on the space of the holography interference fringes.  
     CONSTITUTION: When measured subject 6 is placed on measurement board 7, deformed board 9 is deformed to 9'. The wave surface of board 9 is recorded to hologram 13 so that the reflected light sent from board 9 may overlap the reference light sent from light source 12. Accordingly, the holography interference fringes possessing the interference fringe space occur concentrically in proprtion to the deformation from board 9 to 9'. The holography fringes are picked up by pickup tube 14, and the video signals are applied to arithmetic processor 15. Then the space of the interference fringes is obtained through processor 15, and then the weight of subject 1 is obtained based on the space of the interference fringes and via the relation decided by the deformation property of board 9. And the result of the weight calculation is displayed on display unit 16. In this case, the space of the interference fringes can be obtained easily by means of the horizontal scanning line passing through the center of the concentric pattern since the center of the concentric pattern has no shift.

Title: Motion adaptive yc separator
Inventor: YASUKI SEIJIROU
IPC: H04N9/78
Filed: 1987-03-26
Abstract: PURPOSE:To prevent the degradation in picture quality, dot disturbance, and cross color of oblique stripe components by detecting the direction and the distance (motion vector) moved from a preceding picture to a current picture and shifting the preceding picture by an extent corresponding to the motion to read out it from a memory. CONSTITUTION:A motion vector detector 10 detects a motion vector 11 from the preceding frame to the current frame with respect to a moving picture part. This motion vector 11 is led to an address controller 12, and a read address control signal 13 of a frame memory 4 is generated in accordance with the motion vector 11. The frame memory 4 outputs the preceding frame after correcting the position of the moving picture part of the preceding frame by the address control signal 13 so that this position is matched to the position of the current frame. Consequently, a difference signal 7 between an input signal 1 and a signal 5 of the motion-corrected preceding frame is a small value and a mixture ratio of an inter-frame difference signal 9 is increased because the signal 5 of the preceding frame is so read out that it overlaps the current frame even with respect to the moving picture part. Thus, the degradation in picture quality is prevented.

Filed: 1989-03-24
Abstract: PURPOSE:To prevent malfunction by switching a sound multiplex matrix circuit to a monaural more forcibly even if a dummy pilot is detected in monaural broadcasting by detecting whether or not there is a 2nd sound carrier frequency component. CONSTITUTION:As for a 2nd sound carrier, a carrier detecting circuit 25 detects whether or not there is the carrier simultaneously with FM detection.
